FILING ENVELOP OR- BOX.

Application filed April 29, 1915.

To all whom it may concern: I

Be it known that I, SAMUEL G. HUFFMAN, a citizen of the United States, residing at Lincoln, in the county of Lancaster and State of Nebraska, have invented certain new and useful Improvements in Filing Envelops or Boxes, of which the following is a specification.

This invention relates to filing envelops or boxes and has as its object to provide a filing envelop or box which may be sold in knocked down form and readily and quickly set up for use, and in which drafts, certificates of deposit, checks, and various other papers may be conveniently filed and protected.

It is one aim of the invention to so construct the filing envelop or box that, when set up, it will assume a true rectangular form and will not be liable to become accidentally opened or sag, or become otherwise distorted.

Another aim of the invention is to so construct the box that the blank from which the same is formed may be conveniently printed upon, and further to so construct the box that both ends thereof will present smooth and unbroken surfaces so that matter may be printed upon the said ends to indicate the nature of the contents of the envelop or box.

Another aim of the invention is to so construct the envelop or box that all of its walls will present smooth and unbroken exterior surfaces and that no flaps will be exposed at the exterior of the box and liable to become torn or disconnected.

The invention also aims to so construct the envelop as to effectually exclude dust from the interior thereof.

In the accompanying drawingsz'Figure l is a perspective View of the filing envelop or box embodying the present invention, the same being shown open. Fig. 2 is a similar view of one end of the box illustrating the said end partly closed. Fig. 3 is a vertical transverse sectional. view through one end of the box. Fig. 41 is a plan view of the blank from which the box is formed.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawings by the same reference characters.

The envelop embodying the present invention is formed from a blank, such as shown clearly in Fig. 4 of the drawings, and the envelop when formed up from the Specification of Letters Patent.

blank is rectangular in shape and access may be had thereto through the top thereof, the envelop being adapted to be closed by a closure flap or cover integral with one side wall of the envelop.

The blank comprises side walls 1 and 2 connected by the bottom of the envelop, which bottom is indicated at 3, the blank being scored at the line of juncture of the sides with the bottom to permit of the sides being folded to vertical position. Each end wall of the envelop consists of three interlocked flaps which are integral with the ends of the side walls 1 and 2 and the bottom wall 3. The flaps which are integral with the side wall 1 are indicated by the numeral 4; those which are integral with the side wall 2'are indicated by the numeral 5; and, the flaps which are integral with the bottom 3 are indicated at 6. Each flap 4 is of a width equal to the width or height of the side wall 1 and each of the said flaps is formed with a relatively wide notch extending inwardly from that edge of the flap which constitutes a continuation of the free or upper edge of the said side wall 1. This notch is indicated at 7 and the side walls thereof, indicated at 8, are parallel to each other and extend at right angles to the said edge of the flap, the inner or end wall of the notch, indicated at 9, extending at right angles between the side walls 8 of the said. notch. The formation of the notch 7 in each of the flaps 4 results in a tongue 10 located at what is the free upper corner of the flap in the set up condition of the box. Each of the flaps 5 is of a width substantially equal to the width or height of the side wall 2 and that edge of each. flap 5 which is the upper edge in the set up condition of the box constitutes a continuation of that edge of the side wall 2 which is the upper edge of the said wall in the set up condition of the box. Opposite the said edge of the flap 5, the flap is cut away or recessed to form a tongue 11 which projects downwardly in the set up condition of the box, and which has a diagonal edge 12 extending at an acute angle to the edge of the body of the flap, the said edge of the body being indicated at 13. In a line coincident withthe edge 13, each flap is formed with an incision 14 which serves a purpose to be presently explained. Each of the flaps 6 is of a width equal to the width of the bottom wall 3 of the envelop and of a height equal to the width of-either side wall, and each of the said flaps is provided with a transverse score line 15 defining a terminal tab 16 having an integral tongue 17. blank further includes a top 18 which may be integral with the upper or outer longitudinal edge of either side wall,although here shown as integral with the said edge of the Wall 2, the blank-being scored at the line of juncture of the said top with the said side Wall... The top 18 at its opposite longitudinal edge is formedwith an" integral flap 1 notch 7 until the flap 4: at the lower end of this notch engages in the incisio-nl hin the manner clearly shown in Fig. 2;- The flaps are then further folded in so as to assume an overlapped position, as shown in Figs. 1 and 3 of the drawings, and when they assume this position, the incision 1% will be located at that wall of the notch 8 which is located remote from the juncture of the flap 4 with the wall 1. The flaps 6 are then folded up to vertical position and against the outer sides of the overlapped flaps at and 5, and each flap 6 is then folded on the score line 15 so that the tab 16 will lie.

against the inner sides of the said overlapped flaps 4 and 5 and the tongue 17 is inserted into the pocket formed between the body portion of the flap 4: and the tongue 11 of the fiap .5, the mouth of this pocket being defined by the lower or inner wall 9 of the notch 7 With the parts thus assem bled, the flaps a and 5 will'be securely interlocked and relative outward movement of the side walls 1 and 2 will'be prevented and the flap 6 will securely hold the fiaps4 and top 18 is foldedover and the flaps l9 and 20 are'inserted into the envelop in position lying respectively against'the side wall 1 andthe tongues 16 of the flaps 6.- "In order that the envelop may be securely held closed, 7 a tape 21 is threaded through'spaced incisions 22 formed in the side wall 2 of the Copies of this patent may be obtained for The five' cents each, by'addressing' the Washington, D. C.

box and this tape is tov be passed transversely around the box and tied at its ends.

From the foregoing description of the invention and by reference to Fig. 1 of the drawings, itrwill be observed that none of the interlocking tongues or tabsare exposed at the exterior of the box but that, on the other hand, the walls of the box are exterio'rly smooth-[and unbroken and, conse-- quently, may be printed 'or written upon to any extent and in any manner desired.-

' Having thusrdescribed the invention,

what is claimed as new is:

A filing envelop including sides, a bot- 7 tom, and ends, the said ends comprising overlapped fiaps carried by the sides, one of the overlapped flaps ateach end of the envelop being provided with a relatively wide notch and the other flap being pro vided with a tongue portion laterally spaced with respect to thefree lateral edge of the said flap, the said free-lateral edge of the flap being parallel to the line of juncture of the flap with the associated side, wall of the envelop, the said tongue being of a length less than the length of the flap and that edge of the tongue which is located next adjacent to the free lateral edge of the flap extending in a line diverging from the said free lateral edge of the flap in the direction of the extremity of the tongue, the said'flap' at the line of junctureof the tongue therewith being formed with a slit extending in alinement with the said free lateral edge of the flap, andflaps carried by the bottom of the envelop at the ends thereof'and exteriorly overlapping the first mentioned Iflaps, I

ing its extremity terminating short of the lower edge of the said first mentioned flap, 7 the said slit in thesecond-mentione'd flap having its edges engaging opposite sides of thefirst mentioned flap below the lower end of the notch in the said first'mentioned flap. the flaps upon the bottom being provided with a tab inserted at the lower end of the notch in the'first mentioned flap'and be- Commissioner of Patents,
